“What too would fear profit, unless "the gracious and merciful Lord" gave "meat unto them that fear Him"? [Psalm 111:5]; meat that does not spoil, "bread that comes down from heaven," which He gave to no deservings of ours. For "Christ died for the ungodly." [Romans 5:6] No one then would give such food, save a gracious and merciful Lord. But if He gave so much to this life, if the sinner who was to be justified received the Word made flesh; what shall he receive when glorified in a future world? For, "He shall ever be mindful of His covenant." Nor has He who has given a pledge, given the whole.”

“He hath given meat to them that fear him,.... Or a "prey" (h), alluding to the spoil of the Egyptians; or to the manna; corporeal food, daily bread, which they that fear him shall not want, Psa 34:9 spiritual meat, such that endures for ever; the flesh of Christ, which is meat indeed; the word and ordinances, in which are milk for babes, and meat for strong men; savoury meat does God give his people, such as their souls love, and the world knows nothing of; all is given, and freely given, and in plenty. He will ever be mindful of his covenant; made with Abraham, and that at Sinai; and especially which he made with his people in Christ before the world was; and which is the ground and foundation of all his works of grace and redemption, and the reason why he gives food unto them; he never forgets that, his promises in it, nor the blessings of it, nor the people for whom they are made and provided, nor his love unto them; he is a covenant keeping God. (h) "praedam", Montanus, Vatablus, Musculus; so Ainsworth.”

“Food. Manna in the desert, and what is necessary for us who were in distress in Babylon, Psalm cvi. 5. In the spiritual sense, (Calmet) He has given us Jesus Christ, (St. Augustine) or the holy Eucharist. (Worthington) — St. Chrysostom understands the word of God, (Calmet) which profits those only who fear the Lord, (Berthier) and serve him with love. (Haydock) — Covenant. God has not acted contrary to the covenant with Abraham, in proposing the gospel, which was all along foretold, as St. Paul shews. (Berthier) — He will for ever protect his Church, and shew forth the powerful operation of his death, and of all his mysteries. (Worthington)”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
